Foreword
GB/T 18898 "Erbium Doped Fiber Amplifier" is divided into two parts.
---Part 1.C-band erbium-doped fiber amplifier;
---Part 2.L-band erbium-doped fiber amplifier.
This part is Part 1 of GB/T 18898.
This section was drafted in accordance with the rules given in GB/T 1.1-2009.
This part replaces GB/T 18898.1-2002 "Erbium-doped fiber amplifier C-band erbium-doped fiber amplifier".
Compared with GB/T 18898.1-2002, in addition to editorial changes, the main technical changes are as follows.
---Modified the scope of application of this part, including extended C (C) band erbium-doped fiber amplifier (see Chapter 1,.2002
Chapter 1 of the edition).
--- Deleted erbium-doped fiber amplifier, output signal power, maximum output signal power, gain, small signal gain, input power range,
Output optical power range, input light reflection, output light reflection, noise figure, polarization dependent gain, polarization mode dispersion, maximum total output
Power, input pump leakage power, output pump leakage power, forward ASE power level, reverse ASE power level,
Maximum light reflection tolerance at the input end, maximum light reflection tolerance at the output end, working wavelength range, input reference surface, output reference surface, wave
Channel gain, multi-channel gain change (inter-channel gain difference), gain cross penetration, multi-channel gain change difference, multi-channel gain
Slope (rate of gain change between mutual channels), channel increase/remove gain response (steady state), channel increase/remove instant gain response
Response, channel increase/remove transient response time constant, channel noise figure, channel signal spontaneous radiation noise figure, carrier-to-noise ratio, carrier
Wave composite triple beat ratio and carrier composite second beat ratio are terms that are already in GB/T 16849 "General Specification for Optical Amplifiers"
And definitions (see Chapter 4 of the.2002 edition).
---Added signal to total ASE power ratio, gain slope, gain fluctuation, pre-stored channel, residual channel, loading rise time, download
Terms and definitions for fall time, transient duration (settling time), transient gain overshoot, transient gain undershoot, transient gain deviation
Righteousness (see Chapter 4).
---Added the classification of erbium-doped fiber amplifiers for multi-channel digital transmission applications, divided into fixed gain amplifiers and variable gain amplifiers
Two types (see 5.1).
---Modified the scope of application of erbium-doped fiber amplifiers for analog applications, and is limited to optical fiber analog transmission applications in CATV systems
(See 5.1, 3.1 of the.2002 edition).
---Modified the working temperature range, working humidity and storage temperature technical requirements of all types of EDFA, and added erbium from each type
The technical requirements of optical fiber amplifiers are removed from the table and listed in "6.4 Recommended Environmental Conditions" (see 6.4,.2002 edition
Table 1~Table 13).
---Deleted the laser safety level requirements in the performance parameter table of various erbium-doped fiber amplifiers in the technical requirements, unified in 6.7
Listed (see 6.7, Table 1~Table 13 of the.2002 edition).
---In the performance parameter requirements of erbium-doped fiber amplifier for single channel and analog transmission, the "signal to total ASE power ratio" is added
Performance indicators (see Table 1, Table 2, Table 3 and Table 7).
---Modified the operating wavelength range of single-channel BA, PA and LA (see Table 1, Table 2 and Table 3, and Table 1, Table 2 and Table 2 of the.2002 edition)
table 3).
---Modified the single-channel BA maximum total output power and polarization-related gain parameters, and added the single-channel BA polarization mode dispersion parameters
Requirements (see Table 1, Table 1 of the.2002 edition).
---Modified the single-channel PA input power range, output power range and reverse ASE power parameters, and deleted the forward ASE power
And the maximum total output power parameters, (see Table 2, Table 2 of the.2002 edition).
---Modified the single-channel LA input power range, polarization-dependent gain, reverse ASE power, gain and polarization mode dispersion parameters, deleted
In addition to the forward ASE power parameters (see Table 3, Table 3 of the.2002 edition).
---Modified the method of specifying the performance parameters of multi-channel erbium-doped fiber amplifier according to the number of channels and transmission rate, and changed it to erbium-doped fiber
The type of amplifier specifies its performance parameters, and correspondingly increases the technical requirements for the extended C(C) band erbium-doped fiber amplifier.
Increased gain fluctuation, gain slope range, transient gain overshoot, transient gain undershoot, transient stability time and transient gain deviation
The requirements of other parameters (see Table 4 to Table 6, and Table 4 to Table 12 in the.2002 edition).
---Modified the operating wavelength range, input power range, maximum total output power, input end of the erbium-doped fiber amplifier for analog transmission
The requirements of the maximum light reflection tolerance and the maximum light reflection tolerance parameters of the output end have increased the polarization-dependent gain, polarization mode dispersion, and reflection.
To ASE power and output pump leakage power parameter requirements (see Table 7, Table 13 of the.2002 edition).
---Added the requirements for the content of the logo and the location of the logo in the appearance requirements (see 6.5, 6.1 of the.2002 edition).
---Added the requirements of environmental protection compliance (see 6.6).
---Modified the standard of multi-channel erbium-doped fiber amplifier gain and noise figure measurement method (see 7.4, 7.5,.2002 edition
6.5).
---Modified the standard of the polarization mode dispersion measurement method (see 7.8, 6.9 in the.2002 edition).
---Modified the carrier-to-noise ratio (C/N), carrier composite triple beat ratio (C/CTB) and carrier composite second beat ratio (C/CSO) test settings
The requirements for the carrier-to-noise ratio of the backup system have increased the requirements for the length and type of the test fiber link, and the reference for the test method of the spectrum analyzer has been added.
Technical standards (see 7.9).
---Increase the transient performance parameter test method (see 7.10).

Laws and requirements, increase the fiber side tension, fiber bending requirements (see Table 9,.2002 edition of 7.1).
--- Delete the requirements for low temperature (static) test, high temperature (static) test and damp heat test, delete the high temperature aging test requirements (see
7.2 of the.2002 edition).
---Increase electrostatic discharge, low temperature storage/thermal shock, high relative humidity storage, high temperature storage/thermal shock, constant humidity and heat, temperature cycling, work
